T 0 all whom it may concern: I

Be it known that I, NELSON HARIEY FORBES, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in a inge, of which the following is a specifica tion.

This invention relates to improvements in. hinges of the character described and claimed in Patent 1,486,371, granted to me March 11, 1924.

One of the important objects of the present invention is to-provide a hinge wherein means is associated therewith for detachably securing the same on an automobile door.

A further object of the invention is to provide a hinge of the above mentioned character, which includes a means for strengthening the portions of the door and frame of an automobile with whichthe same is associated, the hinge being of such construction as to be entirely concealed when the door is in a closed position.

A further object of the invention is to provide a hinge of the above mentioned character, which is simple in construction, inexpensive, strong and durable and fur-- thermore adapted for the purposes for which it is designated; 7

Other objects and advantagesof this invention will become apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of the hinge embodying my invention showing the same applied; 7 p

Figure 2 is a horizontal sectional view, through a hinged structure such: as shown in Figure .1, whereby the door and jamh are in reverse positions from that shown in Figure 1. V

Figure 3 is a detail elevational view of the hinge.

Figure 4 is a view similar-to Figure 2 showing a modification. v v

Figure '5 is an elevational view of the hinge illustrated in the modification-and Figures '6 and 7 are diagrammatic views of the bearings associated with the hingesv showing the manner in which {the same are disposed with relation to the door.

' In the drawinga wherein for the purpose of illustration is shown the preferred embodnnent of my invention, the numeral 1 designates a portion of an automobile door, the frame usually associated therewith being illustrated generally at 2. A substantlally L-shaped plate 3 is secured on the upper corner of the door 1 by any suitable fastening means shown at 4:. The portion of the L-shaped bracket 8 which is disposed on the edge of the door 1 is provided with an extension 5 which fits in a suitable cut out portion provided therefor in the inner face of the door.

scribed. p v A similar L-sha-ped plate 6 is secured to the frame 2 inicooperative relation with the L-shaped plate 3, the same being secured to the frame and the usual roof rail of the au-v tomobile by the fastening elements 7. A face .pla tef8' is associated with the L-shaped plate 6 and is adapted to, be secured to the frame on the inner side thereofas clearly illustrated in Figures 1 and 2 of the drawings. The L-shaped plate 6 is disposed on the frame 2 as is also the plate 8 in such a manner as to conceal the cavity 9 provided in the frame asclearly illustratedoin Figure 2. The portion of the L-shaped plate 6 adjacent the edge of the door 1 has formed therein an arcuate slot. The reinforcing member 10 associated with the L-shaped plate 6 and the face plate 8 is also provided with an arcuate slot for cooperation with the arcuate slot I formed in the L sh'aped plate 6. V

Adapted for slidable movement within the ,arcuate slots provided in the plate 6 and the reinforcing member 10 respectively is thexcurved arm 11, the inner portion of which is reinforced as illustrated at 12. The inner end of the curved arm 11 is secured .in a detachable manner on the L-sha'ped plate Bsec-ured on the corner of the door 1 by means of the inward extension 13 which terminates an angular portion 14 for co- -operat1on with the extension 5 formed on the ,plate 3, a set screw 15 being threaded through the extension 14 and into ,a suitable threaded opening provided therefor in the extension 5 as clearly illustrated in Figure ,Qof the drawings. A .pin 16 is carried by the extreme forward end ofthe curved-arm 11 and S-adapted to be disposed in a suitable opening provided therefor indicated at 7 a. The purpose of the eX- tension will hereinafter be more fully de-.

v trated in Figure 2.

17 in the lug 18 which extends laterally from the opposite side of the portion of the Lshaped plate 3 which is disposed on the edge of the door 1. When the set screw 15 is in position within the openings provided therefor in the extensions 5 and 1 1 respectively, and the pin 16 is disposed in the opening 17, the curved arm is supported against displacement from the Lshaped plate 3 of the door 1 and when the door is in a closed position, the curved arm is disposed within the cavity 9 as clearly illus- When the door 1 is in its closed position, the hinge is entirely concealed and is not visible from the exterior of the car.

By swinging the door outwardly in the directionof the arrow, the curved arm 11 will slide within the arcuate slots provided therefor in the. angular plate 6 as well as the reinforcement 10 associated therewith so the door may freely be swung to the position shown in the dotted lines in Figure 2. Also cooperating wit-h the curved arm 11 are the guides 19 which are secured on the L- shaped plate 6 on opposite sides of the arouate slots in the manner more clearly illustrated in Figure 3.

In Figures 1 and 5 of the drawing, a modification is shown wherein the angular plate 20 which is secured to the door 1 has supported on the portion thereof disposed over the edge of the door the detachable spaced lugs 21 and 22 respectively. The lugs are provided with registering openings and the opening in the lug 22 is preferably internally threaded. The arcuate or curved shaped arm 23 which is adapted for slidable movement through an arcuate slot provided in the angular plate 24L secured on the frame of the door and the reinforcement 25 associated therewith has associated on the in ner end thereof the extension 26 which is adapted to be disposed between the lugs 21 and 22 and the extension 26 is provided with an opening 27 adapted for registry with the openings in the lugs 21 and 22 7 whereby a locking bolt 28 extends through the registering openings in the lugs and the extension 26 and is threaded into the threaded opening provided in the lug 22 whereby the arm 23 will be carried by the door.

The free end of the arm 23 has extending laterally therefrom the projections 29, the purpose thereof being to provide a means for limiting the disengagement of the curved arm from the substantially V-shaped spring 30 which is associated with the reinforcement 25 and is disposed within the cavity provided in the door frame, the end of the free arm of the V-shaped spring 30 being provided with a cut. out portion 31 for receiving the curved arm 23 and through which the arm is adapted to slide when the door is moved to an open ora closed posi tion. The lugs 29 will engage the V-shaped spring 30 and thereby prevent the displacement of the curved arm therefrom.

In Figures 6 and ,7 of the drawings, the bearing associated with the hinges of the above mentioned character are illustrated and the same are disposed in such a manner with respect to the door of either a closed or open automobile as to permit the automobile door to be swung to perpendicular open position regardless of the curvature of the automobile body. The bearings 32 and 33 are not in alignment with the face of the door and the frame but are arranged in such a manner as to be,in alignment with each other whereby binding of the door will be prevented.

The provision of a hinge of the above mentioned character enables the same to be readily and easily secured in position on an automobile door and when it becomes necessary to detach the door from the hinges, it is only necessary to remove the set screw 15 with respect to the construction shown in Figures 1 and 2 whereby the pin 16 may be disengaged from the opening 17 and with reference to Figures 1 and 5 of the drawings, by removing the bolt 28, the door may be readily and easily detached. Furthermore the provision of the Lshaped plates in the manner above described will reinforce the door and the frame and render the same strong and durable.

While I have shown the preferred embodiment of my invention, it is to be unplerstood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.

Having thus described the invention, what I claim is 2- 1. A hinge comprising a pair of substan tially Lshaped members adapted to be secured to a door and the adjacent edge of the usual frame therefor respectively, the Lshaped member associated with the frame being disposed over a cavity provided in the frame, a reinforcement associated with the Lshaped member carried by the frame and disposed within the cavity, said Lshaped member and said reinforcement having an arcuate slot provided therein, a curved arm slidable within said slot, the free end of said arm being adapted to be disposed within the cavity in the frame, and

means for detachably securing the curved being disposed over a cavity provided in I the frame, a reinforcement associated with the L-shaped member carried by the frame and disposed Within the cavity, said L-shaped member and said reinforcement having an arcunte slot provided therein, a curved arm shdable Within said slot, the free end of said arm being adapted to be disposed Within the cavity in the frame, means for detachabiy securing the curved arm at its opposite end on the L-shnped member secured to the door, said means comprising an extension associated with the inner end of the curved arm and means for securing the extension on the L-shaped member secured on said door.

In testimony whereof I 211th; my signature.
